[making a web page force a payment before forwarding to the information page]

You will need to set up 2 parts: A front end that they enter the data, and view the results, if and only if the payment is made, as well as a back-end that will verify the payment, and if it processes it, have it store that in a database so you know to show them the data.  AJAX would be best for this.  If you had code, I would help further.

[PHP+MySql Select]

That would be an AJAX request.

[Foreach question]

foreach isn't the best method for what you are doing:

<?php

$search->setsearchname($_POST['queryString']);

$results = $search->results ();

for ($i=0;$i<11;$i++){

echo "<li> <a href=\"suggest.php?mid=".$res->imdbid()."\">".$res->title()." (".$res->year()."</a></li>";

}

So I can understand fully, you want to redirect to a different page while keeping the GET variables? If so, That should be pretty simple.

[Question regarding $_POST, $_SESSION and the original page]

a simple method would be to add this to the top of your first page:

header("Pragma: private");
header("Expires: " . date(DATE_RFC822,strtotime("+1 hour"))); // Change this to how long you are willing to have them go back

[How to make subdomain by php]

mod_rewrite doesn't work for creating sub domains, to my knowledge.  sub domains require A or CNAME records, or they don't work. 

He was almost right. You need a wildcard A record (*.yourdomain.com), then you need to add it to your vhost, then here's an example .htaccess file to get it done:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^[^.]+\.example\.com$
RewriteRule !^index\.php$ index.php [L]

an easier method would be to add the CentOS testing repo:

[Email using PHP]

<shameless plug>

I built an open-source system to send e-mail for you. It's not automated (yet), but it has all the RFC stuff already built in (opt-in/opt-out), multi-user support, and you can modify the code so you can have it grab your users, or I can write a script to import them into my scripts database.  Remember, It's open source. Free as in beer and freedom:

[Rewriting script that uses fopen()]

I prefer to use fopen, read the data, and make sure there isn't any errors from there.

 

/* Define the file, so we can use the name to check size of the file in the future. Much faster when dealing with a large number of files */
$file = "/home/myuser/info.txt";

/* Open the file for reading */
$fh = fopen($file, "r");
/* Read the file, in its entirety */
$data = fread($fh, filesize($file));
/* If reading the file failed, or if it is empty, throw an error. If not, move on */
if (!$data || empty($data)){
echo "[-] Error : couldn't read $file";
exit();
}
/* do whatever you are planning on doing from here */

/* Close the file */
fclose($fh);

This sounds like a javascript issue, and IE is known to have a less than ideal javascript engine.  I've been playing with the dev release of IE9, and I gotta say: that problem may be fixed when it comes out.

[Using exec() to get md5sum of a file, having a problem...]

you could do this:

$file = "$current_dir/$filename";
$file = addslashes($file);
$md5 = md5_file($file);

This way, you don't need to exec the script to get the md5.

['IF' you can help on this, that would be great]

I didn't modify your code aside from clean it up. Before, your code was hard to read. This should be easier. It's also how most people code (roughly. One of the perks of PHP is that you can "freestyle" your code, and it will still work).
[code=php:0]

$_columnCount = $this->getColumnCount();
$prodsPerRow = 3;

$product_image_title = $this->htmlEscape($_product->getName());
$product_image_tag = $this->htmlEscape($this->getImageLabel($_product, 'small_image'));
$product_image = $this->helper('catalog/image')->init($_product, 'small_image')->resize(150, 150);

[Java to PHP help]

I don't have the javax.servlet code, and I'm not a huge fan of compiling from jar if I don't have to.  Basically, from what I've googled, javax.servlet is just a package that makes running http requests easier. Your script appears to be the java equivelent of an AJAX call, minus the call.

 

Basically, what it says:

#Javascript is the closest thing I can think of
function doPost(requestURL, requestString){
    var response = new XMLHttpRequest();
    if (response.responseText == ""){
          alert("empty result!");
    }
    else{
          alert(response.responseText);
    }
}

This is hastily written, and missing a bunch, but that's what the servlet is for. It makes it so you don't have to write the complete call yourself.

 

[Java to PHP help]

I'm no java expert, but this script just writes HTML, and upon success, it closes the script, right?

 

Just wanting to make certain what it does. About to run it through Eclipse now, to see if I have the servlet.http, etc.

[display page , when a link is clicked]

Seeing how PHP works, you will need to use AJAX for this.  PHP processes the source file, and outputs the data that is requested, then it's done.  It does not pause for client-side inputs.  Might want to go to the AJAX section to learn how to make those kinds of calls.
